Before I get through to the site where I put in my card details and pay I get an error with:
This currency is no longer supported.
Tap or click on the currency below and choose another option
I've tried to change my payment in every currency available, all from Austrailian dollars to Uruguayan peso, but it just give my the same error every time.
I'm facing this issue as well. AirBNB support tried says it is a "known issue" and their solution was to let my reservation request cancel, then try again. Very frustrating.
